Transient Modelling of Cavity Receiver Heat Transfer for the Compact Linear Fresnel Reflector

An investigation into unsteady flow patterns in the cavity receiver of the Compact Linear Fresnel Reflector was performed using computational methods. Results indicate that periodic or even chaotic flow patterns may occur for some conditions and cavity designs. However, the results indicate that unsteadiness in the flow structure does not result in significant variation in the over heat loss rate from the cavity.
